Well, that is unfortunately something that is usually not done and shipped with the distro, since it's too specific for a special generations of a system and the function is even given w/o this. May I suggest that we pick this up in the release notes, like:
" Performance tests showed that it is beneficial to use striding RQ with RoCE Express 2(.1) PCIe cards (ConnectX-4) on IBM z14 and LinuxONE Rockhopper II / Emperor II and newer - but by default it is not used. Hence if one has RoCE 2(.1) hardware plugged in to such a system the enablement of striding RQ should be considered, like: ethtool --set-priv-flags <ifname> rx_striding_rq on For the reason of persistence one may also create a service file that sets this during boot-up. " Would that be ok make sense? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868113 Title: [Ubuntu 20.04] Striding RQ as Default for ConnectX-4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1868113/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
